POCKETfBOMB.

Specification of Letters Patent.

Patented Oct. 15, 1918.

Application med may 25, 191s. serial No. 236,495.

To all whom it may conc-em:

Be it known that I, JOZEF G1EDA, a citizen of Russia, residing atVVilkes-Barre. in the county of Luzerne and State of Pennsylvania, .haveinvented certain new and useful Improvements in Pocket-Bombs, of whichthe following is a specification.

The primary object of the invention is the provision of a bomb of smalldimensions for readily carrying in the pocket to be thrown as a handgrenade, the same, however, being especially adapted for use inaeroplanes and adapted to explode at a predetermined future time.

A further object of the invention is the provision of a hand bombadapted for hurling at the enemy and designed to produce a plurality ofsubstantially simultaneous explosions suitably timed for occurring whenthe bomb reaches a desirable location for doing damage in its course-oftravel.

A still further object of the invention is to provide a pocket bomb thatis simple in construction and can be readily loaded and assembled nearthe line of action, the device being capable of disassembling if founddesirable, while the explosive employed is preferably fuse ignited.

In the drawing forming a part of this application, like referencecharacters refer to corresponding parts throughout the several views,and

Figure 1 is a diametrical sectional view;

Fig. 2 is a transverse sectional view thereof taken upon line H-II ofFig. 1;

Fig. 3 isa detail perspective view of a port-ion of the outer casingshowing one of the keeper notches employed; and

Fig. 4 is a perspective view of an edge portion of the coverillustrating the catch employed with said keeper notch. y

The invention primarily consists in a cupshaped casing 10 having anaxially arranged circular wall 11 positioned therein, while a circularcover 12 is mounted for overlying the casing 10 as well as the wall 11thereby closing the central chamber 13 of the housing and the annularchamber 14C between said housing and casing.

An .annular depending flange 15 of the cover 12 closely fit-s within theopen end of the casing 10 and is provided with L-shaped resilientcatches 16 secured to the outer periphery of the flange 11 by means ofscrews 17. Keeper notches 1S are provided 1n the inner face of the wallof the casing 10 adapted to receive the outwardly projecting angularends 19 of the catches 16 when the cover 12 is in position. The flange15 has cutaway portions 20 inwardly of each catch 16 thereby permittingthe catches to shift while flexing, it being understood that the` ends19 of the catches will ride upon the innerface 21 of the casing 10 untilsaid ends reach a position for droppinginto the notches 18. Incline-dend walls 22 are provided for the notches 18 on which ends 22 the catchportions 19 are adapted to travel upon revolving the cover 12 whendesiring to remove the cover. Vhen the catch ends 19 are removed fromthe notches 18 in this manner, the cover 12 can be readily pried andlifted off of the casing`10.

The housing 11 has a plurality of rows of perforations 23 therethroughand a plurality of fuses such as 24 are positioned through an opening 25in the bottom 26 of the casing 10 and extended through slots 27 at thebottom of the wall 11 for positioning the ends of the burning portions28 of the fuses in the explosive material 29 of the annular chamber 1-1.rI`he fuses 21 are firmly secured in the opening 25 by means of suitablesealing material 30 and the device is prefer'- ably formed of castmetal.

The complete operation of the device will Vso be apparent from thisdetail description, it

being seen that when the cover 12 is removed from the casing 10, theexplosive material 29 may be placed in the chamber 14, while the centerchamber 13 formed by the wall 11 may be completely filled with theexplosive 31, the fuses 14 having been previously placed in theperforations 25 with the inner ends thereof in the annular chamber 14.The cover 12 is then secured upon the casing 10 and the device beingsmall enough for carrying in the pocket is readily thrown at the enemyslines or dropped from an airplane after first igniting the fuses 24which are of any desirable length. The explosive material 29 will befirst ignitedi by the fuses 2-1 while the central explosive material 31will be ignited thereby through the perforations 23 and a rapidsuccession Of explosions of these two explosives will occur. Theexplosives 29 and 31 may be of different kinds and being in separatechambers o f the device may be packed or arranged in dllferent. mannersas required by such explosives.

What I claim as new is:

A cup-shaped casing having keeper through, time fuses extending through'the bottom of the casing and through the adjacently positioned openingsof the circularV Wall and terminating in the annular chambei` formedbetween the circular Wall and casing, explosive material within saidannular chamber and Within the chamber formed oy the circular Wall, anda removable cover upon said casing and Wall having detachableconnectionwith thev said notches.

- In testimony whereof I afiixmy signature.

JOZEF GIEDA.
